seeding problem?

[ceres]

I´ve created a torrent and upploaded it to a torrentsite. And it starts of seeding, like it should. With 100% and upploading, but after a while the percentage starts decreasingand after a day, or so it´s down to 90%.

Anyone knows whats wrong?

I´ve made and upploaded loads of torrents before and this has never happened before.

Thanks
